Summary

What does the PR accomplish, why was it needed?
BuildNvidiaDriverContainers.sh generates a string COMPONENT_VERSION to pass to generate-container-sbom.sh when generating an SBOM. COMPONENT_VERSION typically looks like this 550.54.15-3_6.6.57.1.7, but recently a new package "cuda-open" was added, causing this variable to contain both version numbers separated by a newline:

Component Version             -> 560.35.03-1_6.6.64.2.7
560.35.03-1_6.6.64.2.7

This causes an incorrect parameter to be passed to the SBOM script.
